A32NX - Managed climb not working after a go around and diversion

Hi folks. I’m flying the FBW A32NX and cannot climb/descent in managed mode after I go around and make a diversion to an alternate airport. I have to fly only using OP CLIMB and OP DES modes, even if I insert the new destination, new FL and route in FMGS.

Am I missing any steps or this is a A32NX’s limitation?

Thank you in advance.
